Across
  1. 4. the main pigment found in chloroplasts of plants; green in color
  2. 5. called the "powerhouse" of the cell because this is where the second stage of cellular respiration takes place and a great deal of energy is released
  3. 7. H2O; essential for photosynthesis to take place, a product of cellular respiration
  4. 9. CO2; essential for photosynthesis to take place, a product of cellular respiration
  5. 10. provides almost all the energy used by living things on Earth
Down
  1. 1. sugar; a product of photosynthesis, needed for cellular respiration to take place
  2. 2. process in which cells break down simple food molecules such as glucose and release the energy they contain
  3. 3. the process by which a cell captures energy in sunlight and uses it to make food
  4. 6. an energy-releasing process that does not require oxygen; energy level is much lower than that of cellular respiration
  5. 8. O2; a product of photosynthesis, sometimes needed for cellular respiration to take place
